... Abstract Operators of Gulf of Mexico (GOM) wells frequently reported overtorque issue of bottomhole assembly (BHA) connections when drilling the 26-in. section through salt. Such overtorque often leads to costly tool damage beyond repair (DBR), additional trips, and high nonproductive time (NPT...

... positioning (DP) era, many drilling contractors and operators lacked an evidence-based approach for identification of potential process safety and well control failure points. Noble Corporation, a global offshore drilling contractor, (the Company or the Drilling Contractor) has undertaken a journey...

... through interbedded formation triggering drillstring vibration, hard and abrasive sandstone and pressure transition. In most exploratory areas where operators are currently active, the water depth is greater than 4,000 ft. As a result, long drill strings are required which increase the likelihood...

... The novel metal-to-metal sealing and anchoring system was designed to set and seal inside the operator's 10.125-in., 81-lb/ft casing and to hang 7.75-in., 46.1-lb/ft liner. The basis of design was the service provider's ISO 14310/API 11D1 V1-Type qualified hanger. Recognizing the previous testing...

... Nodal analysis compared the base case with the last historical production and the new gun hanger technique. The perforating operation and surging treatment resulted in production of approximately 1,750 BOPD with 0% water cut. This represented a production increase of 90% and a 25% increase...

... Abstract Multilateral and intelligent well construction and completion technologies has proven themselves to be effective means of increasing recovery rates and improving operational efficiencies in subsea wells, yet, there are no known applications where both technologies have been applied...

...) more than standard SET. The increase provides operators with a critical additional casing string deep in the wellbore. These advances ensure that SET technology will play an increasingly prominent role in HPHT wellbore construction as operators optimize wellbore casing designs and reduce risk...

... to as the "plastering or smear effect". This is thought to be due to the proximity of the casing to the wellbore resulting in cuttings being smeared against the formation creating an impermeable mud cake whereas the space between drill pipe and the wellbore, in conventional drilling operations, does not promote...

... demonstrated the ability to remotely monitor distant drilling operations and aid in improved decision-making process for reduced trouble time and improved process safety. Abstract As shown by the Macondo blowout, an uncontrolled deepwater well control event can result in loss of life, damage...

... The Meta Casing Reconnect™ system is a ‘life of well’ solution eliminating costly side tracks and lengthy fishing operations. The product was originally developed for use in the North Sea as a drilling contingency for stuck casing where subsea wellheads were being used. The simplicity...

...Forties Sidetrack Challenges Today, successful development of the Forties field, requires the operator to drill a highly deviated wellbore sidetracked from an existing borehole. Studies on Forties have shown that hole instability is a frequent problem just outside milled casing windows...

... Abstract The Integrated Under-Reamer (IUR) was developed in 2007 in a joint project between an Operator and Service company. The tool was designed to allow for unlimited opening and closing of the tool to provide selective hole opening in unstable formations e.g. unstable shale or swelling salt...

... to a total depth of 32,013 ft in 4,050 ft of water. Shell now serves as the operator and holds a 55% working interest, Anadarko holds a 20% working interest, and Statoil holds the remaining 25%. Three subsequent appraisal wells were drilled by Shell, from October 2009 – April 2010. Bottomhole locations...

... Abstract Casing centralization is one of the key elements to ensure the quality of a cementing job by preventing mud channeling and poor zonal isolation. Centralizers can also assist in running of the casing and prevention of differential sticking. The challenge that both operators and service...

... ( Fig. 3 ) were installed in series on the suction pipe, downstream of the subsea pump, enabling the operator to isolate the AGR subsea pump from the riser and revert back to the conventional drilling process at any time if drilling standard EC-Drill wells. The block valves are fail-safe closed...

A major component of the Hadrian-5 well capping plan was demonstrating wellbore integrity was sufficient for well capping. To facilitate the evaluation...

A recent application in deepwater Gulf of Mexico (GOM) allowed a major oil and gas company to perform a step change in technology that enabled the operator to perform the function more rapidly and at reduced expense. Swellable packers were used instead of cement, providing a novel...
